Finally understood why does a 2-port measurement on a network analyzer can reliably find the impedance of a Power Distribution Network. The RF impedance between power and ground is nearly zero on a PCB with many capacitors, diverting 99% current coming out from port 1 to ground, meanwhile port 2 is in parallel, but its 50 Ω input impedance is large and gets almost no current, no voltage drop. Like Kelvin sensing but instead of 1 MΩ, 50 Ω is large enough. And since port 2 receives almost no power, S21 goes to zero and impedance equation simplifies to a straight line Z = 25 Ω x S21, really neat. #electronics

@Inkscape is celebrating the release of Inkscape 1.1! Among the highlights are a Welcome dialog, a Command Palette, a revamped Dialog Docking System, and searchable preference options. https://inkscape.org/news/2021/05/24/welcome-inkscape-11/

I have encountered more image descriptions on Mastodon in 24 hours than I have in Twitter in a couple of years. Seriously. I'm not exaggerating.
As a blind person, this means a lot to me. If you read this and you describe your images, thank you so, so, so much on behalf of all of us. If you don't, now you know you'll be helping random Internet strangers make sense of your posts by typing in a few more words than usual.

Check out our final report from our tech intern, Kofi "Rukky" Oghenerukevwe -- she was able to build, test, and publish a CiviCRM extension that will help the FSF receive Bitcoin and Litecoin payments! https://u.fsf.org/3bo
